Abstract

PURPOSE: To improve the cleaning efficiency of air in a room by a method wherein an air duct, having an air passage, connected to an air suction port, and a suction port, positioned on a ceiling in a building, is attached detachably to an air cleaner main body, provided with the suction port and the discharging port of air on the casing thereof. CONSTITUTION: An air duct 9 is constituted of an air passage on a suction port 2, provided on the air cleaner main body 5, and a suction port 11, opened on the air passage, extended to a ceiling, at the ceiling. The air duct 9 is attached detachably to the casing 1 through mounting screws 12. In this case, the air duct 9 can be attached to and detached from the air cleaner 5 and when the air duct 9 is attached to the air cleaner main body 5, the upper opening of the air duct 9 is positioned near the ceiling and the lower opening of the same is connected to the air suction port 2 of the air cleaner main body 5. Accordingly, air, drifting near the ceiling, can be sucked surely into the air cleaner main body 5 upon operating the air cleaner main body 5 whereby the cleaning efficiency of air in the room can be improved remarkably.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier installed and used in a room of a building, for example.

[0002]

2. Description of the Related Art For example, there are various types of floor-standing air purifiers that are installed and used on the floor of the room for the purpose of collecting and deodorizing indoor air. There is a structure as shown in FIGS.

That is, reference numeral 1 denotes a casing of an air purifier, and inside the casing 1, a dust collecting device, a deodorizing filter, and a blower (not shown) are installed. Further, intake ports 2 are provided on both left and right side surfaces and an upper surface of the casing 1, and a cleaning air discharge port 3 is provided on a front bottom portion of the casing 1. 4 is a caster provided on the bottom,
The air purifier 5 having such a configuration can be moved on the floor surface 6 by using the casters 4 and can be installed at an appropriate position.

[0004]

However, in the air cleaner 5 for floor installation having such a structure, the height thereof is not as large as the left side, and the intake port 2 provided in the housing 1 thereof.
Since the position of is low, for example, it is difficult to inhale smoke such as cigarettes rising in the ceiling direction in the room, and there is a problem that the dust collection and deodorizing efficiency of smoke generated in the middle to upper layers of the room is particularly poor. there were.

[0005]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to such a conventional problem. One end opening is located in a ceiling of a room, and the other end opening is an intake port of an air purifier body. An air duct connected to the air purifier is detachably attached to the main body of the air purifier to suck gas such as cigarette smoke rising near the ceiling in the room into the air purifier, thereby purifying the room air. An object of the present invention is to provide an air purifier that can efficiently perform the above.

[0006]

EXAMPLES The present invention will be described in detail below with reference to the examples shown in FIGS.

In the drawings, reference numeral 5 denotes an air purifier body, and since the air purifier body 5 has the same structure as that of the air purifier described in the conventional example, the same reference numerals are given to the same structural parts and the air thereof is designated. A description of the structure of the purifier body 5 is omitted. As shown in FIG. 7, inside the main body 5 of the air purifier, inside the housing 1, a dust collecting deodorizing filter 7 is arranged close to the intake port 2 and communicates with the discharge port 3. Blower 8
Is decorated.

Reference numeral 9 is an air duct, and the air duct 9 is provided on each of the intake ports 2 provided on the left and right side surfaces of the air purifier body 5, and the respective air passages 10 are attached to the air passages 10.
And both of these air passages 10 communicate with each other and extend to the ceiling of the room, and the suction port 11 opens at the ceiling.
The air duct 9 extends over both sides of the casing 1 by means of mounting screws 12 and is attached to the casing 1.
It is detachably attached to.

Further, when the air duct 9 is attached to the housing 1, a sealing material 13 is provided on the joint surface between the air duct 9 and the housing 1 in order to enhance the airtightness between the air duct 9 and the housing 1. It is intervening. Reference numeral 14 represents a drive switch provided in the air purifier body 5.

The above-mentioned structure of the present embodiment and its characteristic feature is that the air duct 9 can be attached to and detached from the existing stationary air purifier main body 5, and the air duct 9 can be attached and detached. When attached to the air purifier body 5, the upper opening of the air duct 9 is located near the ceiling in the room, and the lower opening is connected to the intake port 2 of the air purifier body 5. During operation of the air purifier body 5 to which the air duct 9 is attached, it is certain that the air drifting in the ceiling of the room is sucked into the air purifier body 5, and the efficiency of cleaning the air in the room is high. Is significantly improved.

Further, since the air duct 9 is attachable to and detachable from the air purifier body 5, the air duct 9 is, for example,
Wearing the air purifier body reduces construction costs (equipment costs) compared to using air ducts installed in the ceiling due to indoor construction (building construction), and significantly improves economic efficiency. The air duct 9 can be freely moved to a desired position (location) together with the main body of the air purifier, and highly efficient air purifying can be performed according to a request.

If the air duct 9 is removed from the air purifier body 5, the air duct 9 can be used as a normal air purifier without causing a feeling of strangeness.

[0013]

As described above, according to the present invention, the air purifier body 5 in which the air intake port 2 and the air discharge port 3 of the housing 1 are provided.
On the other hand, since it is an air purifier in which the air duct 9 having the ventilation passage 10 connected to the intake port 2 and the suction port 11 located near the ceiling in the building is detachably attached, For example, at the time of operation of the air purifier body 5 to which the air duct 9 is attached, it is sure that the air drifting in the ceiling of the room is sucked into the air purifier body 5, and the cleaning efficiency of the room air is improved. Remarkably improved.

Further, since the air duct 9 is attachable to and detachable from the air purifier body 5, the air duct 9 is, for example,
Wearing the air purifier body reduces construction costs (equipment costs) compared to using air ducts installed in the ceiling due to indoor construction (building construction), and significantly improves economic efficiency. It is possible to freely move the air duct 9 together with the air purifier body to a desired position (location),
It is possible to perform highly efficient air purification in response to requests.

If the air duct 9 is removed from the air purifier body 5, the air duct 9 can be used as a normal air purifier without causing an uncomfortable feeling, and the actual benefit is great.
